Apologies if this is the wrong place to ask this but, I’m running: AMD Ryzen AI 9 HX 370 w/ RX7700S (2nd Gen), and I’ve been hit with the whole “Fans Not Detected” error.
I believe it to be a false status error as it’s shown up for 7040 Series but, have no real recourse at this point, I think?
I’ve swapped my RX7700S out for the Empty Expansion Bay for now and the error has gone away. I’m just wondering if there’s been any mention of an update, like the 4.03, that fixes it? Something applicable for the 300 Series?
I’ve had this issue right after upgrading the motherboard to the HX 370. The very first boot was normal, but all subsequent attempts showed a “fan not detected” warning, and the cpu clocks were limited to ~0.5Ghz (probably a hard limit of a few watts for the CPU).
I tried multiple time reconnecting everything, swapping back from the RTX 5070 module to the 7700S or the empty expansion bay, using a different interposer, with no changes.
My motherboard (batch 1) was shipped with BIOS 3.00. I proceeded to do a BIOS update to 3.04 (from LFKN6.03.00 to LFKN6.03.04) and, after a reboot, the fan warning was gone and the clock speed was back to normal.
I haven’t had the issue since then. Either it was a bug in the 3.00 BIOS, or updating the BIOS did reset some settings I was not able to see…
I have the same issue on my FW16 AI 350 with BIOS version 3.04.
After a lot of back and forth with the support, they send me a replacement mainboard. However, this did not solve the fan detection error for me, this is getting frustrating.
Anyway, I’d be happy if you could keep us updated on the debugging progress.
I went some time with my RX7700S (2nd Gen) removed, finding that the “fan not detected” issue went away. Having just reinstalled the dGPU, the error has gone. I’m wondering if it’s less about the Motherboard and maybe more about the dGPU?
It’s strange. I was able to avoid the “fan not detected” issue by switching back to the base version of the Framework 16 laptop (empty shell, no dGPU). I stuck with that for just over a week, then now swapped back.
I didn’t get a “fan not detected” alert but an “interpose door not closed” error. After making sure it was properly closed, it booted with no problem. dGPU access, and everything.
I’ll keep an eye on it the next couple of days. If any more errors turn up, I’ll reach out to support.
Is there any way I could monitor the fans? Or power to the fans, or do you have any suggestions for what I should be on the lookout for? At least until things flare back up again (which it might, as there’s been no real change to software).
Edit: For context (AMD Ryzen AI 9 HX 370 w/ RX7700S (2nd Gen), BIOS 3.04).
Thanks for the update! I don’t have a dGPU, so I sadly can’t test that.
Now, I even got a full laptop replacement by support, and the error still shows up. So I’m really starting to suspect that this is a bios problem and not a hardware problem.
Interesting that you see an impact depending on what is in the bay. For me, at least reseating the fans does essentially nothing. But then, the fans were always detected in the BIOS menu, they were always spinning under load for me. It’s just this empty error.
I opened a Github issue, you could comment there with a summary of your issues/fixes to bump the priority a bit:
